/**
  EFI Socket Library Constructor

  This routine supports an implementation dependent constructor
  depending upon whether the library is linked to a socket
  application or the SocketDxe driver.  The following modules
  declare the redirection for the constructor in ::mpfnEslConstructor:
  <ul>
    <li>StdLib/EfiSocketLib/UseSocketLib.c - Application links against EfiSocketLib</li>
    <li>StdLib/SocketDxe/EntryUnload.c - SocketDxe links against EfiSocketLib</li>
  </ul>

  The EfiSocketLib.inf file lists ::EslConstructor as the CONSTRUCTOR
  in the [Defines] section.  As a result, this routine is called by
  the ProcessLibraryConstructorList routine of the AutoGen.c module
  in the Build directory associated with the socket application or
  the SocketDxe driver.

  @retval EFI_SUCCESS       The socket layer initialization was successful

/**
  EFI Socket Library Destructor

  This routine supports an implementation dependent destructor
  depending upon whether the library is linked to a socket
  application or the SocketDxe driver.  The following modules
  declare the redirection for the destructor in ::mpfnEslDestructor:
  <ul>

    <li>StdLib/SocketDxe/EntryUnload.c - SocketDxe links against EfiSocketLib</li>

  The EfiSocketLib.inf file lists ::EslDestructor as the DESTRUCTOR
  in the [Defines] section.  As a result, this routine is called by
  the ProcessLibraryDestructorList routine of the AutoGen.c module
  in the Build directory associated with the socket application or
  the SocketDxe driver.
